Answer:
Variable overhead efficiency variance= $3,000 favorable
Explanation:
<u>To calculate the variable overhead efficiency variance, we need to use the following formula:</u>
Variable overhead efficiency variance= (Standard Quantity - Actual Quantity)*Standard rate
Standard quantity= 3*15,000= 45,000 hours
Actual quantity= 44,000 hours
Standard rate= $3 per hour
Variable overhead efficiency variance= (45,000 - 44,000)*3
Variable overhead efficiency variance= $3,000 favorable
